ABSTRACT:
A weather strip for doors and windows of the casement and awning types, primarily for domestic use, and the like, made of two different thermoplastic materials, one being relatively flexible but having sufficient mechanical rigidity so as to prevent shrinking or stretching of the weather strip when installed, and the other being considerably more supple and flexible. The weather strip has a T-shaped base with anchoring means on the vertical bar of the T-shaped base, and two supple wings made of the more flexible material, extending parallel to one another but spaced apart and secured to the opposite end portions of the horizontal bar of the T-shaped base. This weather strip, which can also take some other forms, particularly in respect of its gripping leg, defines between its supple wings an air space which constitutes an excellent thermal barrier between inside and outside conditions which is particularly useful in cold climates. Moreover, the flexibility of the thin wings ensures easy opening of the door or window so equipped in view of the fact that yielding of the double wing arrangement necessitates very limited opening force. The wings are sufficiently long as to permit proper weather stripping even if the clearance around the hinged panel of the door or window is not perfectly uniform.
